Method For Forming A Packaging Material In Multilayered Band

Abstract

A method for forming a packaging material in multi-layer band ( 2 ) includes feeding a first band ( 3 ) of thermo formable material and at least a second band ( 4 ) along respective first and second feeding paths (P 1, P 2 ), which extend through a station ( 10 ) for joining the first band ( 3 ) and the second band ( 4 ). The bands ( 3, 4 ) are joined, by sealing, in the joining station ( 10 ), in order to obtain a third, multi-layer band ( 2 ) fed along a third feeding path (P 3 ). Moreover, the method includes another step, during which at least one of the bands ( 3, 4, 2 ) undergoes a process for defining a visual, three-dimensional effect image on the band.

1 . A method for forming a multi-layer band ( 2 ) packaging material, the method including: feeding a first band ( 3 ) of thermo formable material and at least a second band ( 4 ) along respective first and second feeding paths (P 1 , P 2 ) extending through a joining station ( 10 ) for joining said first band ( 3 ) and said second band ( 4 ); joining, by sealing, said bands ( 3 ,  4 ) in said joining station ( 10 ) for obtaining a third, multi-layer band ( 2 ) fed along a third feeding path (P 3 ); the method being characterized in that it includes another step for processing at least one of said bands ( 3 ,  4 ,  2 ) for defining a visual, three-dimensional effect image on the band.  
   
   
       2 . A method as claimed in  claim 1 , wherein said image defining processing is performed at said joining station ( 10 ).  
   
   
       3 . A method as claimed in  claim 1 , wherein said image defining processing is performed upstream of said joining station ( 10 ).  
   
   
       4 . A method as claimed in  claim 1 , wherein said image defining processing is performed on said third band ( 2 ) downstream of said joining station ( 10 ), along said third path (P 3 ).  
   
   
       5 . A method as claimed in  claim 1 , wherein said first band ( 3 ) and said second band ( 4 ) are unwound from the respective bobbins ( 5 ,  11 ); said image defining processing being performed on at least one of said first and second bands ( 3 ,  4 ) before or during their winding on the bobbins.  
   
   
       6 . A method as claimed in  claim 1 , wherein said image defining processing is a mechanical process for printing a hologram on said band ( 3 ,  4 ,  2 ).  
   
   
       7 . A method as claimed in  claim 6 , wherein said hologram is defined by a digitalized photographic image.  
   
   
       8 . A method as claimed in  claim 6 , wherein said hologram is defined by either a logo, or a name, or a trademark, or the like.  
   
   
       9 . A method as claimed in  claim 6 , wherein said hologram is defined by at least one alpha-numerical code.  
   
   
       10 . A method as claimed in  claim 6 , wherein said hologram is defined by a Braille coded wording.  
   
   
       11 . A method as claimed in  claim 1 , wherein said process is a mechanical process for printing a filigree on said band ( 3 ,  4 ,  2 ).  
   
   
       12 . A method as claimed in  claim 1 , wherein said third band ( 2 ) is a blister band ( 2 ) with articles ( 9 ), obtained by the reciprocal joining of said first thermo formable band ( 3 ), consisting of a blistered band ( 3 ) with blisters filled with said articles ( 9 ), and said second band ( 4 ), consisting of a closing band ( 4 ) for sealing said blister band ( 3 ).  
   
   
       13 . A method as claimed in  claim 11 , characterized in that said articles ( 9 ) are pharmaceutical articles.  
   
   
       14 . A blister pack ( 13 ) obtained by cut-division of a blister band ( 2 ) according to the method claimed in the  claim 11  or  12 .
